=head1 NAME

FS::phone_avail - Phone number availability cache

=head1 SYNOPSIS

  use FS::phone_avail;

  $record = new FS::phone_avail \%hash;
  $record = new FS::phone_avail { 'column' => 'value' };

  $error = $record->insert;

  $error = $new_record->replace($old_record);

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::phone_avail object represents availability of phone service.
FS::phone_avail inherits from FS::Record.  The following fields are currently
supported:

=over 4

=item availnum

primary key

=item exportnum

exportnum

=item countrycode

countrycode

=item state

state

=item npa

npa

=item nxx

nxx

=item station

station

=item name

Optional name

=item svcnum

svcnum

=item availbatch

availbatch

=back

=head1 METHODS

=over 4

=item new HASHREF

Creates a new record.  To add the record to the database, see L<"insert">.

Note that this stores the hash reference, not a distinct copy of the hash it
points to.  You can ask the object for a copy with the I<hash> method.

=cut

# the new method can be inherited from FS::Record, if a table method is defined

sub table { 'phone_avail'; }

=item insert

Adds this record to the database.  If there is an error, returns the error,
otherwise returns false.

=cut

# the insert method can be inherited from FS::Record

=item delete

Delete this record from the database.

=cut

# the delete method can be inherited from FS::Record

=item replace OLD_RECORD

Replaces the OLD_RECORD with this one in the database.  If there is an error,
returns the error, otherwise returns false.

=cut

# the replace method can be inherited from FS::Record

=item check

Checks all fields to make sure this is a valid record.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.

# the check method should currently be supplied - FS::Record contains some
# data checking routines
